Defining the blank form

If you wish to use the TNC's graphic workpiece simulation you must first
define a rectangular workpiece blank. Its sides lie parallel to the X, Y and Z
axes and can be up to 30,000 millimeters long.

The ratio of the blank-form side lengths must be less than 200:1.

MIN and MAX points

The blank form is defined by two of its corner points:

• MIN point: smallest X, Y and Z coordinates of the blank form, entered

as absolute values.

• MAX point: largest X, Y and Z coordinates of the blank form, entered

as absolute or incremental values.

MIN and MAX points define the
blank form.
